Yeh well you can re-use but I find balls a pain, alot of heavy shifting in and out of the tray not to mention a cunt to dispose of
Jim as far as the plant count goes mate it really is just that simple, if he put more smaller plants in there they would yield just the same but obviously in a shorter amount of time due to less veg.
It's all about the canopy bro, what sees light will turn to bud.
16 plants just as big as the 6 would need twice the space.
I'm not following the 16 just as big as 6, that would require the other half of the container,
I dunno Jimmy, I must be missing something.
Peace n pipes.
